SPECIFICATION forming part of Letters lPatent No. 724,348, dated lMarch 31V, 1903. Application iil'ed O'otber 29, 1901-. Serial No. 801410. (No model.)

To @ZZ whom t 11i/ay concern,.-

Be it known that ,1, SAMUEL CURTTS SPAN- GLER, a citizen of the United States, and a resident of Clyde, in the' county o f Grant and Territory of Oklahoma, have invented anew and Improved Pitching Apparatus, of which the following is a full, clear,'and exact description. f

This invention relates to an apparatus for ro handling grain, hay, andthe like, and is particularly adapted for use in feeding sheaves of grain to a thresher.

This specification is a specific description of one -form of the invention, while the claims i 5 are definitions of the actual scope thereof.

Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar characters of reference indijcate corresponding parts in all the views.

Fig'. 9 is a section on the line 9 9 of Fig. 1, and Fig. 10 is a section 3o on the line 10 10 of Fig. 1. l

12 indicates the baseof the machine, which *is preferably rectangular. .'(See Fig. 3.) On,

this base is mounted a platform 14, on which lis arranged to turn the vertically-disposed. 35 ldrum 15, having a hollow mast 16 hingedly mounted thereon, so that the mast may be thrown down into horizontal position when lnot in operation. `The mast has a collar 17v lfastened loosely to its upper end and guy- -ropes 18 passing from the collar down to the base 12. The d-ru m has an inverted-crown lworm-gear 19 atits bottom, and in mesh with this gear 19 is aworm 20 on a shaft 2l, lmounted horizontally in the base 12. Universally connected to the shaft 2l is a shaft A22, which has a friction-disk 23 thereon. This disk 23 bears between two driving fric- -tion-disks 24, which are mounted in parallel planes on a vertical axis y25 and driven by 5o gearing 26, connecting it with a transverselydisposed primary-movement or drive shaft 27. The shaft 22'is mounted loosely in a box 23, carried on a vertically-disposed rod 29, mounted to slide in a part of the base 12 and connected with a lever 30, passing under the friction-disk 24. This lever is in turn connected to a hand-lever 31, arranged at the rear-end of the base 12. By throwing the hand-lever 3l the levez' 30 will be thrown and the rod 29 raised or lowered, thus engaging the friction-wheel 23 with either of the disks 24, so as to drive the shafts 22 and 2l in either direction desired, and thus revolve the drum 15 to the right or to the left. Removably mounted in the base under the drum 15 and parallel with the shaft 2l are two shaft-s 32 and 33. These shafts are respectively in universal connection with shafts 34 and 35, similar to the sh'aft 22, said shafts 34 and y35 respectively carrying friction-disks 36 and 37. The disks V36 and 37 lie between the disks 24, the same as the disk 23. are mounted, respectively, in boxes 33 and 39, which are carried byrshafts 40 and 4l, similar to theshaft 29. These shafts 40 and 41 are moved up and down by levers 42 and 43, connected with hand-levers 44 and 45, similar andadjacent to the hand-lever 31. 'By these means the shafts`32 and 33may be v turned in either direction.

On the shaft 32 are oppositely wound vtwo cables 46 and 47, and on the shaft 33 is wound a cable'48. These cables are actuated by the rotating shafts to Wind or unwind, according to the direction in which the shafts turn. lrojecting forwardly from the drum 15 is an arm 49, to which is pivotally connected a beam50. This beam has upwardly-projecting guides 5l and 52 fastened thereon, the guide 51 being fastened rigidly to the outer end of the beam andthe guide v52 being slidable on the beam. Faste'ned to the guide 52 is a beam 53, which slides over the top of the beam 50 and through the guidel 51, the beam 53 carrying at its outer end a guide 54, extending vertically. Slidable in the guide 54 is a beam 55, which has a guide 56 at its rear end, which runs on the beam 53.

57 indicates a brace for the guide 51.

The guide 52 carries at its top a sheave 5S, and the guide 54 carries in the same position a sheave 59. Over these sheaves runs an The'shafts 34 and IOC ' beam 55.

endlessvcableV 60, which is fastened at the point 61 to the beam 55 and at the point 60a to the guide 51, whereby to cause the beam 55 to move outward on the beam 53 as said beam and its guide 54 move. The return movement of the beam 53 will by a reversal of the above operation 'cause the beam 55 to return. 4

The cable 48 from the shaft 33 passes up through the mast 16 and over a sheave 62 at the top thereof, thence downward to the upper end of the guide 51.` This cable 48 supports the parts 50, 51, and 55, which constitute the arm of the machine. By drawing the cable 48 in or out the arm may be raised or lowered, as desired. The cable 46 passes through a sheave in the wall of the drum 15 and thence outward-to a connection with the guide 52, and the cable 47 passes in the same mannervbelow vthe arm 49, past the sheave 63 at the lower end of the guide 52, around a sheave 64 at the lower end of the beam 50, and thence back to the inner end of the beam 53, to which the cable 47 is fastened. Now it is clear that by hauling in one of the cables 46 or 47 and slacking o the other the beam 53 and the attached parts may be moved* inward or outward on the beam 50, thus `extending or contracting the arm. In recapitulation, therefore, the lever 31 regulates the turning-movement of the drum 15 and its attached parts, the lever 44 regulates the raising and lowering of the arm of the machine, and the lever 45 regulates the extensionor contraction of the length of the arm.

The fork of the machine is carried at the outer end of the beam 55, and it comprises a vertically-disposed tubular shaft 65, connected at its upper end to turn in a box 66, fastened in a seat formed in the outer end of the (See Fig. 4.) This shaft 65 has a spring 67 connected therewith and with the box 66, and a pulley 68 is fastened to the upper end of the hollow shaft 65. Over this pulley passes a cable 69,which extends through an openingin the beam 55 to the outside thereof and thence inward alongside the beam to a sheave at the inner end of the beam 55. From thefsheave 70 the cable passes around a sheave 7l.at the lower end of the guide 54, and from this latter sheave the cable passes into the drum 15 and downward through the base ofthe machine to a treadle 72. By operating this treadle the tubular shaft 65 may be turned in the box 66 against the tension of the spring 67. By passing the cable 69 over sheaves 70 and 71 in the manner explained the movements of the beams 53 and 55 will not affect the tension of the cable. The purpose of turning the shaft 65, and consequently-the parts attached thereto, is to present the bundle of grain head first to the machine. f

The lower end of thetubular shaft 65 carries a cross-head 73 of cruciform shape, and this is provided with forks or prongs 74, projecting downward to engage the ground.

Lying under the cross-head 73 is a cross-head 75 of essentially the same shape, and this cross-head is connected to a rod 76, which eX- tends upward through the tubular shaft 65. A spring 77 presses downward the'cross-head 75, and this cross-head carries rods 78, which respectively run through the forks 74, so as to actuate barbs 79. When the rods 78 are pushed downward, which occurs under the action of the spring 77, the barbs 79 are thrown outward into act-ive position, and when the rods 7S are raised the barbs 79,be ing tapered, as shown in Figs. 6 and 7, return to inactive position. (See Fig. 6.) The .upper end of the rod 76 is connected by a chain v8O with a lever 81. This lever is fulcrumed on the outer end of the beam 55 and extends downward below it in position to engage the. lower end of the guide 54. As the beam 55 moves inward the lever strikes the guide 54, -and this throws the lever so as to move the rod 76 and its attached parts. Therefore the instant the lever 81 leaves the guide 54 the spring7 7 asserts itself and throws out the barbs 79. Then as the fork is plunged into the grain the barbs hold the grain on the fork. The grain is subsequently released by the return of the lever 81 into engagement with the guide 54.

In the operation of the apparatus the operator stands at the base of the machine and manipulates the various parts to move the grain or other material worked from its resting-place and pitch it, so to speak, into the thresher. It will be observed that the apparatus is under the complete control ofv the operator owing to` the various cables and other gear provided.
